Watching the effects of yet another dose of cum.

Sarah sat against the wall, breathing heavily from the exertion. Marveling at the double creampie she had given Adam, she noticed something else: With every post-orgasmic twitch, his ass and thighs gained a bit more mass, his legs becoming shapelier and shapelier. The vista was undeniably arousing, but after more than a dozen orgasms in a day, Sarah's dicks could only twitch weakly.

She looked down, annoyed. How long would she have to wait until her cocks recovered? She wanted to keep fucking! Also, a harem with only two members just wasn't enough. Without a steady supply of cum, she wouldn't be able to expand it!

Talking about harems - what was Katie doing again? After all, maybe she was done working. Sarah got up and told Adam to get himself cleaned up once he recovered, receiving a happy groan as an answer.

Back in her room, she put Katie's number into her phone and pressed "Call".
